Single Screw Plastic Extruder

SJ Series single-screw extruder is designed with German technology (L/D 33 and 36). Screw is separate type with mixing part. Barrel is grooved feed type with lengthened feeding part. With separate screw and grooved barrel, the extruder has advantages:

  • Optimizing melt process to get high output.
  • Extrusion with low melt temperature.
  • The cut from separate clearance makes material even mixed.
  • Customized screw and barrel according to different material application. 
Application for Single screw plastic extruder:

The single screw extruder performs a high efficiency and reliable performance on PE, PP, PEX, ABS, PA and soft PVC extrusion forming industries. It is windly used in plastic pipe, profile, film extrusion production industry.  

Concentrating on plastic and multi-layer plastic pipe machine developing, Shuanglin offers varietis plastic extruder on different plastic pipe producing. 

  1. High speed extruders for big size pipe extrusion line. SJ120/33 SJ60/36 and SJ90/36, Screw and barrel design is the first important design to make higher rotation speed,  better melting mixing effect, high mould pressure, screw temperature controlable, etc. The best choice for HDPE pipe 500-1600mm extrusion, high speed PPR20-32, PERT16-32 pipe extrusion.
  2. Co-extruder for glass fiber, UV layer, Nano layer, Mark line etc.
  3. Melting Adhesive extruder for PEX-AL-PEX production line. 
  4. Recycling granulator extruder etc.

Large Calibre HDPE pipe extrusion line

HDPE water supply pipe and gas pipe production line. The latest high speed extruder and multi-function haul-off machine saves energy much than traditional ones.

HDPE Solid wall Pipe Advantages

Reference Standard:  DIN 8074-1999, SDR41-SDR11, PE100,PE80,PE63
  1. HDPE is non-toxic, with no heavy metal additives. The HDPE pipe won’t attract dirt or contaminated by microorganism, and is resistant to chemical or electron chemical corrosion.
  2. It’s solid wall structure allow it to withstand high pressure, making it ideal for pressure application like water and gas supply.
  3. It’s light weight and ease of installation can reduce installation costs by as much as 50% compare to metal piping system
  4. Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than metal pipe
  5. Longevity: more than 50 years under proper use
  6. Recyclable and Environment-friendly

Main technical characteristics of Shuanglin HDPE Pipe Extrusion Line:

SHUANGLIN combined the advanced technology and digestion to prompt this HDPE water supply pipe and gas pipe production line. Its unique structure design and high efficiency performance makes it fast accepted by the pipe factories.

The extrusion line consists of high efficiency single screw extruder, vacuum calibration, spraying water cooling tank, multi-claw haul-off machine, planetary cutting machine , pipe stacker and trolley.

It adopts PLC control system and HMI for whole extrusion line, synchronization function realized, as well as the winding machine. It helps the group machine production management and quality control.

This HDPE Pipe production line utilize highly efficient large capacity single screw extruder, vacuum sizing tank, spray cooling tank, various multi-band trackers, planetary cutting machine, and  finished products stacker, equipped with spiral or basket extrusion mold.

With appropriate exchange of certain units, the production line can realize two or three layer co-extrusion of dual resistance pipe. Co-extruded layers of pipe wall have uniform thickness. The inner and outer layer use dual resistance material (flame retardant, anti-static, etc), while the core layer using ordinary HDPE. this way it greatly reduces the amount dual resistance material used , and thereby reducing the cost of dual resistance pipe.

This Pipe Extrusion Line adopts PLC control system, man-machine interface(MHI), easy to operate,  function auto-synchronize.
